“Around half a millennium ago,” Dawn said, “an outworlder came from this world to Pallimustus and fell into the service of a Pallimustus deity. When he acquired the means to return to his own world, he came back with tools and a mission from that deity. He set up a global magical infrastructure that would strengthen the bond between the two worlds. Over the centuries, more and more of the magic building up on Pallimustus was siphoned into this world.”
